Surface density maps of Sextans RHB, BHB, bright and faint BSs, using the same decontamination techniques from Fig. 7, with overlaid iso-density contours with exponentially increasing values until the maximum of the measured map (lowest contour at 2σ detection from the displaced pointing, with the second one at approximately 3σ detection). The ellipse shows the contour of the King profile at its tidal radius derived in this work.
